A thermal pellet holds contact-carrying resilient switch blades in bending stress with the contacts closed. Melting of the thermal pellet relieves the bending stress and allows movement of the switch blades to open the contacts.

An adjustable bimetal snap disc thermostat is disclosed which provides conventional resistance-type heaters symmetrically positioned adjacent one side of the snap disc to allow adjustment of the operating temperature of the thermostat. The heaters are supported by heater terminals which extend up through the thermostat body and cover, and connect the cover to the thermostat body. The heaters and heater terminals are connected as a subassembly and subsequently installed as a unit in a device to minimize assembly costs. Further, since the heaters are conventional commercially available heaters, the cost of the heaters per se is minimized.
